Anoka County Multi-Jurisdictional <br />All Hazards Mitigation Plan <br /> 112 <br /> <br />Geospacial Analysis software from ESRI that Anoka County Emergency Management would <br />like to purchase in the future to provide for additional features in HAZUS-MR. <br /> <br />Qualitative Methodology relies less on technology, and more on historical and anecdotal data, <br />community input, and professional judgment <br />regarding expected hazard impacts. The qualitative <br />assessment is built around varying degrees and <br />weights of risk values as assigned by the consensus <br />of Anoka County’s Hazard Mitigation Steering <br />Committee. <br /> <br />The vulnerability assessment for Anoka County uses <br />a scoring system based on the adjacent table. <br /> <br />Risk Analysis In 2011 Anoka County completed a <br />risk and hazard assessment using Digital Sandbox. <br />The results are being used to assess and review the <br />natural and manmade risks to Anoka County. <br /> <br /> <br />4.4.1.1 Countywide Hazard Vulnerability <br />After analyzing and evaluating all available data, the <br />Hazard Committee developed the hazard history <br />vulnerability assessment. The table below lists the <br />hazards identified by the committee as hazards that <br />have impacted Anoka County and its municipalities <br />in the past and the potential hazards that could <br />impact the county and its municipalities in the future. <br />The committee then used the risk table developed <br />previously to determine the county’s degree of <br />vulnerability to each hazard. <br /> <br />Economically in Anoka County flooding has been <br />most costly with a reported cost of over $204 million, <br />or an average 0f $5.5 million per occurrence. <br />Tornadoes were second at over $123 million. <br />Severe weather-Thunderstorms with hail lightning <br />and high winds ranks third with over $30 million in <br />losses. Urban fires rank 4th with over $15.6 million in <br />losses followed by wildfires which accounted for 6.5 million in losses which includes timber and <br />response costs. Pandemics are the most costly in fatalities and injuries with over 6000 fatalities <br />and injuries followed by tornadoes with over 750 fatalities and injuries. <br /> <br />When historical information for all selected hazards is evaluated and scored, flooding is the <br />number one hazard that has impacted Anoka County. It was recognized that the availability and <br />quantity of data varied significantly between hazards and thus impacted evaluations. The <br />committee believed that had economic data been accurately recorded, urban fires and severe <br />weather dollars could easily have been up to 5-10 times greater. <br />HAZARD RATING <br />No Fatalities/Injuries 0 <br />Less than 3 injuries 1 <br />Less than 5 fatalities/10 injuries 2 <br />Less than 15 fatalities/50 injuries 3 <br />Less than 25 fatalities/100 injuries 4 <br />More than 26 fatalities/injuries 5 <br />No Economic Damage or Cost 0 <br />Less than 500,000 damage cost 1 <br />Less than 2,000,000 damage cost 2 <br />Less than 5,000,000 damage cost 3 <br />Less than 10,000,000 damage cost 4 <br />More than 10,000,000 damage cost 5 <br />Extent area minimal/no evacuation 0 <br />Extent area local/minimal evacuation 1 <br />Extent area local/some evacuation 2 <br />Extent area 1 mi./some evacuation 3 <br />Extent area 3 mi./major evacuation 4 <br />Extent area >3 mile/evacuation 5 <br />Probability once in 100+ years 0 <br />Probability once in 50 years 1 <br />Probability once in 10 years 2 <br />Probability once in every 5 years 3 <br />Probability once in every 1 year 4 <br />Probability more than once in 1 year 5 <br />No repetitive loss 0 <br />One repetitive loss 1 <br />Three repetitive losses 2 <br />Five repetitive losses 3 <br />Ten repetitive losses 4 <br />More than ten repetitive losses 5
